Dr. Elsa Reichmanis is a professor in the School of Chemical and Biomolecular Engineering and holds a courtesy appointment with the School of Materials Science and Engineering.
Elsa Reichmanis’ research interests include the chemistry, properties and applications of materials technologies for electronic and photonic applications, with particular focus on polymeric and nanostructured materials for advanced technologies.
Whether oligomeric or polymer in nature, organic materials have been shown to be attractive candidates for both passive and active roles in electronic devices because of their compatibility with high through-put, low cost processing techniques; and their capability to be precisely functionalized through the techniques of organic synthesis to afford desired performance attributes. Structure at both the molecular and nano-scales will impact attributes such as morphology (surface roughness, grain size), adhesion, mechanical integrity, solubility and chemical and environmental stability. These factors in turn will affect device performance, notably electrical performance (mobility, conductivity, on/off ratio, threshold voltage).
The Reichmanis research group is currently exploring polymeric and hybrid organic/inorganic materials chemistries for electronic applications, plastic electronics in particular. To take full advantage of organic semiconductor technology, solution processed materials are required for conventional mass printing applications. This effort requires the development of compatible device materials and processes. Key to understanding the issues leading to the design of new materials and processes engineered to afford desired characteristics is an understanding of materials morphology in both thin films and single crystals. In particular, the former depends not only on inherent materials characteristics, but is also highly dependent upon the deposition process; vacuum vs solution, temperature (of deposition and anneals), molecular environment surrounding the films, etc. Studies related to the understanding of how materials processing impacts morphology and device performance are underway.
Further, how organic based semiconductors interact with the surfaces of other materials involved in device fabrication is important to defining semiconducting performance. Studies are underway to explore these issues and identify optimal materials sets.
